Process for producing toner

摘要

A process for producing a toner includes melt-blending at least a colorant and a polymer and finely pulverizing the resulting blend after cooling, wherein the polymer is a crosslinked resin having a ratio of weight-average molecular weight to number-average molecular weight (Mw/Mn) exceeding 4.0 and a melt index of 0.01-10 g/10 min. at 110 DEG C. under a load of 10 Kg and the polymer is further crosslinked to form gel during the melt-blending. The toner thus obtained exhibits a good fixability without offset phenomenon over a wide temperature range.
